GENERAL DESCRIPTION
The SGM2019 is a low power, low noise and low dropout voltage RF linear regulator. It is capable of supplying 300mA output current with typical dropout voltage of only 270mV. The operating input voltage range is from 2.5V to 5.5V. The fixed output voltage range is from 1.2V to 3.3V and the adjustable output voltage range is from 1.2V to 5.0V.
Other features include logic-controlled shutdown mode, output current limit and thermal shutdown protection.
The SGM2019 is suitable for application which needs low noise and low power supply, such as MP3 players, palmtop computers, etc. Fixed or adjustable output voltage versions are provided.
The SGM2019 is available in Green SOT-23-5 and SC70-5 packages. It operates over an operating temperature range of -40℃ to +85℃.
